Webminimum of E is attained in the convex hull of D, since the approximant xm is derived as a convex combination of xm−1 and ϕm. In this paper, we introduce a new greedy algorithm based on one dimen-sional optimization at each step, which does not require the solution of (1.1) to belong to the convex hull of D and has a rate of convergence O(m1 ... WebThis paper discusses a data-driven, cooperative control strategy to maximize wind farm power production. Conventionally, every wind turbine in a wind farm is operated to maximize its own power production without taking into account the interactions between the wind turbines in a wind farm. Because of wake interference, such greedy control strategy can …

WebA greedy algorithm is a simple, intuitive algorithm that is used in optimization problems. The algorithm makes the optimal choice at each step as it attempts to find the overall optimal way to solve the entire … Webtake greedy strategies to iteratively select one examples af-ter another, which is however suboptimal compared with optimizing a set of selections at a time. In this paper we propose a non-greedy active learning method for text categorization using least-squares support vector machines (LSSVM). Our work is based on trans-
WebDec 18, 2007 · This paper investigates convex optimization strategies for coordinating a large-scale team of fully actuated mobile robots. Our primary motivation is both algorithm scalability as well as real-time performance. To accomplish this, we employ a formal definition from shape analysis for formation representation and repose the motion …
